Photo acid Generators
(Photo Initiators for cationic polymerization)CPI®-100P, CPI®-101A, CPI®-200K, CPI®-210S

CPI-100P and CPI-101A are triarylsulfonium salt type photo acid generators (Photo Initiators for cationic polymerization) with few impurities and are mainly composed of mono-sulfonium salt. When compared with conventional products containing large amounts of bis-sulfonium salt, CPI-100P and CPI-101A have excellent solubility with organic compounds and storage stability with various compositions.

CPI-200K and CPI-210S are triarylsulfonium salt type photo acid generators with environment-friendly and non-antimony type special phosphate-based anions developed in-house. Though they are phosphorous-based, they show the same effectiveness as antimony systems. The cation structure of the above CPI series can absorb i-lines (365 nm), and the structure is suitable for photocuring pigment types and clear-type cation polymerizable monomers used in masking applications (required for i-line sensitivity) and alicyclic epoxy.

Currently, our company is preparing the development of photo acid generator (PAG) products with higher i line and g-h line sensitivity than traditional products.
